DISPENSING nEvioE.

Application ma March 2 1, 1927. Serial No. 177,602.

This invention relates to dispensing devices and the object of the invent-ion 1s to provide a device for dispensing paste fro a tube. I

' One of the particular objects ofthe invention is to provide an arrangement whereby the tube is sealed except when paste is being;

dispensed from the tube- Another object of the invention is to pro-c vide a paste dispenser in which the paste tube is arranged to turnon a pivot for dispensing the paste, the sealing member being turned Fig. 1 is a side elevation of a dispensing device embodying our invention.

Fig. 2 is a plan view of a port-ion of the dispenser.

Fig. 3 is a bottom view of the portion of the dispenser shown inFig. 2.

Fig. 1 is a'section taken on line 4 1. of Fig. 2. j I i f Fig. 5 is a section taken on line 55 of Fig. 3.

As shown in Fig.1 the device comprises a sheet metal base 1 having two upwardly exstem 5 extending through the standard 2 and which is preferably squared at the end and a disc 6 is provided with a squaredaperture at the center fitting overthe squared end of the stem 5. This disc is secured in place by the screw 7 which extends through a washer 8 and into the end ofthe stem 5. This disc is provided with a C shaped rib 9 as shown in Fig. 3 and a pin 10 is secured in the outer edge ofthe disc 6 centrally between the ends 12 is preferably provided with a squared end extending into the base 1. A member 13 is provided with a squared aperture fitting the squared end of the stem 12 and a screw let the spring in position.

extends through a, Washer-'15 and is threaded into the stem 12 to secure the member 13 theretor This member 13 is shown more par ticularly in Fig. 3 and is provided with two arcuate faces 16 and'17 and with a slot 18 in which the pin 10 on the disc. 6'is adapted to engage similar to a Geneva action. As shown in Figs. 1, 2 andt a discharge nozzle 19 is pro vided into which the threaded end of the paste tube 20 is threaded. The nozzle 19 isprovided with a longitudinal aperture 21 through which the paste from the tube 20 may pass and this nozzle is secured in the member 4:- by means of a threaded sleeve 22 which is threaded into an aperture provided therefor in the member 4. The member llis provided at the upper end with a. cylindrical casing 23 in which a member 24 is longitudinally move able by the coiled spring 25. The end of, the casing is closed by a plug 26 and the member 2a is provided wit-ha cork seat 27 for the end of the nozzle 19. In order'to maintain the nozzle 19 in the sealed position shown in Fig. 4: the disc 6 is provided with a notch. 28 in whicha depression 29 ina flat spring 30 engages. This flat spring 30 as shown in Figs. 3 and 5 is provided witha lug 31 which is sol dered to the under side of the basel to secure The depression 29 and the notch 28 are rounded so that when the tube 20 is turned by hand to turn the member 4. and disc 6' secured thereto the lug 29 will readily pass out of the notch 28. This depression 29 tends to hold the parts in the position shown in full lines in 2.

The base 1;,is secured to a wall with the parts in thepo'sition shown in full lines in ig. 2. To use the device the paste tube 20 is turned by hand to the position shown in dotted lines in Fig. 2. This turns the disc 6 so that the pin 10 passes out of the slot 18thus turning the member 13 to the dotted position shown in'Fig. 3 and moving the pin 10 to the dotted position; This movement causesthe arcuate face 17 of the member 13 to engage the C shaped rib 9 as shown in Fig. 3 and by this arrangement the casing 23 and closure member 24 are turned as the nozzle 19 is turned. As the tube is turned back to the position shown in full lines in Fig. 2 the pin 10, is moved into the slot 18 of the member 13 and turns the member 13 back to the position shown in full lines in 3 at which time the depression 29 engages in the notch 28 and locks the parts in the closed position. It will be noted thatas the nozzle 19 is turned from the dotted position in Fig.2 to the position shown in full lines in said figure that the end of the nozzle engages in the cork seat 27 and moves the member 24; back slightly ticularly for dispensing tooth paste or shavin g cream it maybe used wherever paste is to be dispensed from a collapsible tube.

From the foregoing description it becomes evident that the device is very simple and eflioient in operation, will not easily get out of I order, allows ready replacement of the paste tube when empty andprovides a device which accomplishes the objects described.

Having thus fully described our invention, its utility and mode of operation, what we claim and desire tosecure by Letters Patent of the United States is- 1. In a dispensing device, a base, a pair of members rotatably mounted in the base, a nozzle supported in one of the members, the nozzle being adapted for'threaded relation with the discharge end of a paste tube, a spring pressed nozzle closure member supported in the other rotatab'lememberand normally closingthenozzle, a disc secured to the rotatable member in which the nozzle is sup ported, a slotted member secured to the other rotatable member, a pin extending from the disc and adapted to engage in the slotted member to turn the slotted member to a limited extent as the disc is turned, the disc being provided with a notch and a fiat spring having an end engaging in the said notch when the nozzle is in-t'he closed position,

' 2. In a dispensing device, a base, a pair of members rotatably mounted in the base,

a'nozzle supported in one of the members,

the nozzle being adapted for threaded rela* tion wit-h the discharge end ofa paste tube, a spring pressed nozzle closure member supported in the other rotatable member and normally closing the nozzle, a disc secured to the rotatable member in which the nozzle is supported, a slotted member secured to the other rotatable member and a pin extending from the disc and adapted to engage in theslotted member to turn the slotted member to a limv ited extent as the disc is turned.

3. In a dlspensmg device, a'base, a pal-not members rotatably mounted in the base, a

nozzle secured to one of the members, the

nozzle being adapted for threaded relation with the discharge end'of a paste tube, a nozzle closure member supported in the other rotatable member, a spring tending to hold the nozz'lec'losure member in position to close.

the nozzle, the two rotatable members being connected together sothat when the nozzle is turned the nozzle closure member is turned away from the nozzle and as the nozzle is returned the closure member is moved into sealing engagement with the nozzle. 1

4. In a dispensing device, a base, a pair-oi members rotatably mounted in the base,-a"noz'- zle secured to one of the members, the nozzle being adapted for threaded relation with the discharge end of a paste tube, a nozzle closure member secured to the'other rotatable mem= her and normally, closing the nozzle and means whereby rotation of the nozzle and its support in one direction turns the nozzle closure member outof contact with the nozzle and subsequent rotation of the nozzle and its support in the oppositedirection moves the closure member into engagement with the nozzle.

In testimony whereof We sign this specifi cation.
